Strong, Weak, and Latent Ties and the Impact of New Media 总被引：2，自引：0，他引：2
Caroline Haythornthwaite 《The Information Society》2002,18(5):385-401
This article argues that consideration of the strength of ties between communicators can help reconcile disparate results on the impact of new media on social relations. It is argued from the research literature and studies by the author that where ties are strong, communicators can influence each other to adapt and expand their use of media to support the exchanges important to their tie, but where ties are weak, communicators are dependent on common, organizationally established means of communication and protocols established by others. Due to this differential use of media, a new medium that adds means and opportunities for previously unconnected others to communicate will have positive effects on weak ties and weak-tie networks, in particular by laying an infrastructure of latent ties (ones that exist technically but have not yet been activated), and providing an opportunity for weak ties to develop and strengthen. A new medium may also have positive effects on strongly tied pairs where it adds another means of communicating and supports the communication needs and tasks of the pair. However, where a new medium replaces a former, common means of communication, the dependence of weak ties on a common medium makes weak-tie networks highly susceptible to dissolution. In contrast, strong-tie networks, with their connections via multiple relations and multiple media, can be expected to be more robust under conditions of change. 相似文献

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius. 相似文献

网络关系强度与企业技术创新绩效——基于探索式学习和利用式学习的实证研究 总被引：1，自引：0，他引：1
网络强弱关系被视为影响企业技术创新的重要因素,然而简单考察网络关系与技术创新两个变量的相关关系并没有获得一致结论,形成了“关系嵌入性悖论”。以探索式学习和利用式学习为中介变量,提出了网络关系强度对企业突破性创新和渐进性创新的两面性作用的假设,构建了网络关系强度对技术创新影响的概念模型,并进行了实证研究。实证分析结果表明：创新网络关系强度的提高不利于突破性创新,但有利于渐进创新的提升,其中网络关系强度通过探索式学习对突破性创新产生负面影响,但通过利用式学习对渐进性创新产生正面影响。对此做了进一步讨论并提出了未来研究的若干展望。 相似文献

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals–is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities. 相似文献

Regional technology clusters are an important source of economic development, yet in biotechnology few successful clusters exist. Previous research links successful clusters to heightened innovation capacity achieved through the existence of social ties linking individuals across companies. Less understood are the mechanisms by which such networks emerge. The article uses social network analysis to examine the emergence of social networks linking senior managers employed in biotechnology firms in San Diego, California. Labor mobility within the region has forged a large network linking managers and firms, while ties linking managers of an early company, Hybritech, formed a network backbone anchoring growth in the region. 相似文献

The strength of strong ties in the creation of innovation 总被引：4，自引：0，他引：4
Katja Rost 《Research Policy》2011,40(4):588-604
There is an ongoing debate in innovation research as to which type of social capital is more conducive to innovation: structural holes as proposed by Burt or network closure as proposed by Coleman. Although Coleman focused on the quality of relationships, Burt argued that the structural configuration of relationships was more important. I argue that, instead of being alternative substitutes, Burt's social capital theory complements Coleman's theory. More precisely, I demonstrate that, in the presence of strong ties, weak network architectures (structural holes or a peripheral network position) leverage the strength of strong ties in the creation of innovation. This implies that weak network architectures have no value without strong ties, whereas strong ties have some value without weak network architectures but are leveraged by this type of structure. The findings indicate that innovation research tends to overestimate the impact of weak network architectures in the creation of innovation. By pointing to the necessity of strong ties, the results may be of particular interest for research on open innovation. They suggest that open innovation will not work if closed innovation principles are pushed back. 相似文献

Is it possible to identify crime suspects by their mobile phone call records? Can the spatial-temporal movements of individuals linked to convicted criminals help to identify those who facilitate crime? Might we leverage the usage of mobile phones, such as incoming and outgoing call numbers, coordinates, call duration and frequency of calls, in a specific time window on either side of a crime to provide a focus for the location and period under investigation? Might the call data records of convicted criminals' social networks serve to distinguish criminals from non-criminals? To address these questions, we used heterogeneous call data records dataset by tapping into the power of social network analysis and the advancements in graph convolutional networks. In collaboration with the Punjab Police and Punjab Information Technology Board, these techniques were useful in identifying convicted individuals. The approaches employed are useful in identifying crime suspects and facilitators to support smart policing in the fight against the country's increasing crime rates. Last but not least, the applied methods are highly desirable to complement high-cost video-based smart city surveillance platforms in developing countries. 相似文献

The technology acceptance model (TAM) has been widely used to study user acceptance of new computer technologies. However, it does not incorporate social structure and influence as a significant factor. In this study, we ask the following questions: (i) What are the limitations of the existing TAM for studying virtual community? (ii) What is effect of social networks on user acceptance of technology for virtual community? and (iii) How can the influence of different types of social ties serve as a basis for exploring the user acceptance of technology in a virtual community? Here, we explore the possibility for extending TAM to incorporate the influence of the different types of social ties as a new theoretical construct. Preliminary analysis of data from a virtual community results show that weak and strong ties influence technology acceptance. The findings enable HCI researchers to account for influence of social ties in future investigations using TAM. 相似文献
